Black is what appears if no answer choices . When illuminated with red light, there's no green light to reflect, and the red light will be absorbed, so the leaf will reflect no light and therefore appear black.

This makes black and other dark colors an excellent choice for sunblocking power. The green parts contain chlorophyll and photosynthesise to make starch. Rather than studying an object's emission of infrared, scientists can study how objects reflect, transmit, and absorb the Sun's near-infrared radiation to observe health of vegetation and soil composition. Light is made up of three different colors: red, blue and green. A leaf is often flat, so it absorbs the most light, and thin, so that the sunlight can get to the chloroplasts in the cells. Due to its structure and its chemical set-up, a leaf reflects infrared light twice as intensely as green light. Can reflected light from below, damage/burn the underside of the leaf?
